Attention Nexus S 4G users: The moment you have been waiting for is finally hitting tomorrow. Android Police reported that the Nexus S 4G would receive the long-awaited Ice Cream Sandwich update tomorrow, according to a screenshot of Sprint’s internal systems (seen after the break). The over-the-air update should hit any time now, so get ready. Let’s hope nothing goes wrong in the process.

First they made a video testimonial featuring a bunch of excited developers. Last week brought us a promo clip they first played back to journalists who attended presser in May. Then came the first official Google Wallet commercial featuring Seinfeld’s George Constanza and his exploding wallet. Today, the search company has officially rolled out Wallet, a mobile payment service.

As you can see from the clip we embedded above, it features Google engineers highlighting the many benefits of paying simply by tapping your phone to a terminal. One thing immediately captures attention: The “hundreds of thousands” of points of sale which support Google Wallet, all MasterCard PayPass terminals. Google promised at the May unveiling they would support more smartphones with an NFC chip in the future, not ruling out a next-gen iPhone. Today, the company wrote in a blog post:

Today, Visa, Discover and American Express have made available their NFC specifications that could enable their cards to be added to future versions of Google Wallet.

If you’re a Sprint customer with a Nexus S 4G device, the Google Wallet app will be delivered as an over the air update. Just tap the Wallet app on your home screen, add your Citi MasterCard credit card or set up a Google Prepaid Card and transfer some funds to it from any of your credit cards and off you go.

Early adopters who set up a Google Prepaid Card before the year’s end also get a $10 free bonus. When you see the Google Wallet logo on a poster, simply scan it with your phone to add the advertised offer or coupon to your Google Wallet account. The below walkthrough by TechCrunch lays out everything you need to know about Google Wallet in Layman’s terms. Good-bye wallet, the phone will take it from here and another from ThisIsMyNext… expand full story

Sprint announced on their blog that they will be unveiling an update to their Nexus S 4G. The update will include tweaks to increase data speed, Wi-Fi connectivity, speakerphone audio quality, and adds TTY support for the deaf and hard of hearing. The update will be dubbed Android 2.3.5 and will be available Monday, July 25th.

Engadget has exclusively received the update to test data speeds. As you can see in the screenshot above, speeds were improved — even enough Engadget says the speed change is noticeable.

When you pay with your phone, it automatically redeems offers and earns loyalty points for you

Boom, Google Wallet has gone live at the just-finished presser in Google’s New York office. The search Goliath means business, that’s for sure. They’ve managed to convince the journos like us who have seen it all that Google Wallet is no toy. We have here an end-to-end mobile payment solution which quite possibly marks an inflection point in e-commerce. I ain’t drinking Google’s Kool-Aid, bear with me for a sec.

There are two pieces to it: Google Wallet itself, which runs as a native app on your mobile device equipped with an NFC chip, and Google Offers, a Groupon-like service providing rebates, savings and offers that can be easily redeemed on your device, at the points of sale. One click on an offer on the web sends the coupon over-the-air to your devices authorized for Google Wallet. You can also use your device’s camera to snap the Google Offers icon found on printed marketing materials such as in-store posters, banners, print ads and so forth.

Paying for goods is a one-tap affair involving waving your device in front of the wireless payment terminal at participating merchants. The transaction is processed within seconds and directly settled with your issuing bank. In addition, your device negotiates with the merchant’s terminal to automatically redeem offers and earn loyalty points for you. Someday, Google boldly proclaimed, stuff like boarding passes, tickets, ID and keys will be stored in your Google Wallet. You will also get electronic receipts that will eliminate bills on paper. Looking good so far. What’s the catch?

The keynote demonstration had Google’s speaker buying a shorts for his daughter. He waived the phone and the clerk’s terminal took into account his loyalty card and automatically deducted his saved coupon. The live transaction was handled successfully in the second try.

So how do you stand out in the crowded Android space? I know – let’s put a bunch of cats in a television commercial, Sprint’s marketing people must have said when pitching creative concepts for the Nexus S 4G campaign to their bosses. The resulting advert is cutesy and a bit mischievous, but not bad at all. Plus, you gotta love the closing line:

It’s the first phone that’s Google to the core with Sprint’s lightning fast 4G speed. It’s powerful enough to do just about anything, including filling the internet with more cats.
